Andrew has three times as many pencils as Noah and five pens he has 17 pens and pencils altogether how many pencils does Noah have. Distributive property and solving equations

9514 1404 393

  4

Step-by-step explanation:

The distributive property does not appear to be involved in this question.

Let n represent the number of Noah's pencils. Then Andrew's total is ...

  3n +5 = 17

  3n = 12 . . . . . subtract 5 from both sides

  n = 4 . . . . . .  divide both sides by 3

Noah has 4 pencils.

step-by-step explanation:

guess at question:

a vertical line intersects the graph of g(x,y) = 0 at two points. what conclusion follows about the function f(x) implicitly defined by g(x,f(x)) = 0?

the domain of f(x) cannot include the x coordinate of any such vertical line.

informally, f(x) is not a function, and

g(x,y)=0 cannot be solved for y uniquely.

the relation r = {(x,y) such that g(x,y) = 0} is a function if

for all (a,b) ∊ r and (c,d) ∊ r, a=c implies b=d.
